The reasons why dogs like to watch people go to the toilet:

1. Dogs are afraid that you are in danger. In the eyes of dogs, going to the toilet is a very dangerous thing, because dogs will relax their vigilance when going to the toilet and are easily attacked. So when you go to the toilet, the dog thinks that you are in danger, so it stares at you and protects you, fearing that you will be hurt.

2. Dogs regard their owners as relatives. After being together for a long time, the owner has been taking care of the dog, and the dog regards you as its closest person. Therefore, it likes to stick to its owner and wants to follow him wherever the owner goes.

3. The dog is in a good mood when looking at you. If your dog loves you, it will be happy just looking at you. According to research by Japanese scientists, when a dog stares at you, it produces a pleasure hormone, so that it can get a lot of pleasure.

4. Dogs are curious about their owners. If a dog likes its owner, it will always be curious about what the owner is doing, so it will be concerned about what the owner is doing in the bathroom, and will also worry about whether the owner is stealing food behind its back.

5. The dog is learning skills with you. Dogs live with their mother when they are puppies. The mother not only takes care of the puppies, but also teaches them certain learning skills. So wherever the mother dog goes, the puppies will follow. After living with its owner, the dog will naturally regard the owner as its mother, so it will do whatever the owner does, and it will follow the owner to the toilet.
